My guess is that few people have stopped to compare them. I've never knowingly seen a 100+hz screen in person, so I stopped by a local store. Sure enough, I could tell that the motion was smoother. Bought 2. After using those, I can feel my older monitors that I'm using to write this are choppy.
But do you notice the smoothness in the day to day basis or have you, in a way, crippled yourself, because now the majority of monitors feel choppy to you?
Sounds a bit like the, 'Never meet your heroes', thingy.
I 100% notice it but interestingly it doesn’t affect me on my laptop/desktop much since I use a mouse and scrolling is already not smooth. While mobile has smooth scrolling and a lot more animations/swipes.
Most flagship Android phones are >60hz and have been for a few years. Flagship iPhones and iPads are >60hz. Very nearly every gaming laptop is >60hz. Many new TVs are >60hz with inputs to match.
True, it's probably just bleeding edge, but i've noticed several flagship phones, have 90HZ, and the new iPad Pros have up to 120hz "smooth scrolling", so it seems something will be happening x years down the line.
